BOOKBINDERS VISE.

' SPECIFICATION forming part of Letters Patent N 0. 727,520, dated May5, 1903.

Application filed May 28, 1902. Serial No. 109,34A- (No model.)

To all whom, it may concern:

Be it known that we, ALFRED H. WHITESIDE and SAMUEL G. CAMPBELL,citizens of the United States, risiding at Logansport, in the county ofCass and State of Indiana, have invented certain new and usefulImprovements in Bookbinders Vises, of which the following is aspecification.

This invention relates to bookbinding, and has special reference to animproved bookbinders vise or stand comprising means for permitting ofthe free use of both hands in the operation of lettering, gilding, orotherwise finishing the back of a book.

To this end the invention contemplates a simple and practicalconstruction of vise designed to support books of various sizes in anupright position within convenient reach of the bookbinder and also insuch a manner that the book can be very quickly removed and replaced.

In carrying out these general objects the invention contemplates aconstruction adapted for general use as a bookbinders vise for holdingthe books clamped in astationary or rigid position for any purpose.

With these and many other objects in View, which will more readilyappear as the nature of the invention is better understood, the sameconsists in the novel construction, combination, and arrangement ofparts, as will be hereinafter more fully described, illustrated, andclaimed.

The essential features of the invention involved in the means for adjustably supporting the book and also in the adjustable and releasablemeans for clamping the book in its upright position are necessarilysusceptible to considerable modification without departing from thespirit or scope of the invention; but a preferred embodiment of thelatter is shown in the accompanying drawings, in

tional View of the Vise, showing one of the ways in which it may beconveniently secured to a work table or bench. Fig. 3 is a detailsectional view showing more plainly the hinged connection between, 3 theswinging bracket andthe adjustable clamp-carrier. Fig. 4 is a detailsectional view showing the slip-clutch connection between the adjustableclamp-carrier or carrier-arm and the supporting member or cleat. Fig. 5is a detail sectional view on the line 5 5 of Fig, 2

Like reference-numerals designate corresponding parts throughout theseveral figures of the drawings.

In carrying out the invention there is necessarily employed a fixedmember or element, against which the book is clamped, and usually thisfixed member or element is in the form of an upright fiat clamping-base1, which is sufficiently wide at the upperportion there of to provide anextended surface, upon which one side of the book bears when clamped upin the vise. The said fiat clamping-base 1 may be supported in anyconvenient manner, but is usually arranged in an upright position and isdesigned to be fastened to a work table, bench, or other pointconvenient to the bookbinder. A simple means of mounting the uprightclamping-base 1 of the vise in .proper operative position is shown inthe drawings and essentially consists in rigidly securing to the rearside of the base, at or contiguous to the upper end thereof, atransverse cleat or bar 2, constituting the supporting member of thevise and having associated therewith a fastening-clamp 3, also securedto the rear side of the upright base and below the plane of the cleat orbar 2, the screw member i of the clamp 3 being adapted to work againstthe under side of the work table or bench, whereby the latter may beclamped between said clamp 3 and the cleat 2, thus providing for rigidlyyet detachably fastening the vise in an operative upright position.

To provide for the support of a book and also for supporting books ofgreatly-varying sizes, there is associated with the uprightclamping-base l a vertically-adjustable rest-platform 5, projectedoutwardly fromthe fixed base 1 and having its supporting-surface for thebook disposed at right angles to the adjacent side of the base, wherebythe book may rest upon edge on the platform 5 and be clamped with itsside flat against the base member 1.

Various expedients may be resorted to in providing for the verticaladjustment of the rest-platform 5 and also for locking the same fast inits adjusted position. Alpreferable construction is shown in thedrawings, and consists in fastening the rest-platform 5 to an adjustableslide 6, adjustable longitudinally upon the clamping-base l andessentially consisting of the oppositely-arranged bindingplates 7 and 8,disposed, respectively, upon opposite sides of the base and one of whichcarries the intermediate slide-block 9, working in the slotted guideway10, formed longitudinally in the base and usually extending the fulllength thereof, as shown in the drawings. The locking-screw 11 passesthrough the binding-plates 7 and 8 and a nut 12. This locking-screw 11when tightened serves to clamp up the separate members of the slide 6,thus securely fastening the rest-platform 5 in any adjusted position.

The clamping of the book against the fiat base 1 is accomplished throughthe medium of an adjustable clamp 13, working in opposition to the base1 at the outer side thereof. This clamp-jaw has a swiveled connection 14with the inner end of a clamping-screw 15, having a hand-wheel 16 at itsother end and working through a nut 17, carried at the swingingor freeend of a swinging bracket or bracket-arm 18. To permit of the adjustmentinward and outward of the clamp-jaw 13 without turning thereof, said jawpreferably has a loosely-interlocked slidable connection with thebracket or bracket-arm 18. A preferable form of this connection is shownin the drawings and comprises a keeper consisting of a pair of spacedholding-pinslQ, projected outward from the outer side of the clamp-jawand sufficiently long to permit of a considerable adjustment of theclamp-jaw. The outer end portion of the bracket 18 is hinged by thehinge-pin 20 to the outer end of an adjustable clamp carrier 21. Thehinge-pin 20 for the bracket 18 is disposed longitudinally withreference to the carrier 21 and transversely with reference to thebracket 18, which is rounded ofi at its rear end, as shown in Fig. 3,whereby the same may swing upwardly and laterally to provide for movingthe clamp in and out of operative position, according as the book is tobe mounted in position or removed. At the point of the hinge connectionbetween the bracket and its supporting-carrier 21 the latter is providedwith a transversely-disposed seat 22 in its upper side, within whichseat the bracket 18 lies flush when in its lowered operative position.It will here be noted that the bracket 18 and the carrier-arin 21constitute a support for the jaw 13.

The adjustable clamp-carrier 21 is preferably in the form of a straightbar and usually extends through a clutch-opening 25, formed in one endportion of the cleat or bar 2. One wallof the clutch-opening 25 isformed with a binding swell or projection 26, against which the carrieror bar 21. is rocked or pressed when the clamping-screw 15 is tightenedup. By reason of this construction it is obvious that the locking of theclamp-carrier 21 is automatic, but when the screw 15 is loosened thesaid bar may be readily slid through the clutch-opening to accommodatethe clamp to any size book.

From the foregoing it is thought that the construction, operation, andmany advane tages of the herein described bookbinders vise will bereadily apparent without further description, and it will also beunderstood that various changes in the form, proportion, and minordetails of construction may be resorted to without departing from thespirit of the invention or sacrificing any of the advantages thereof.

Having thus described the invention, what is claimed,and desired to besecured by Letters Patent, is

1. In a vise of the class described, a fixed upright base, asubstantially horizontal restplatform adjustable vertically on the base,and a support having a jaw-carrying member mounted to move verticallyinto and out of an operative position with respect to the base, thespace between and above the base and the jaw-carrying member beingunobstructed to give access to the back of a book when held in the vise.
